This cylinder begins as Isolde is about to
extinguish the torch, the signal that Tristan may come to her. Mapleson then
stops his machine, resuming for the C major Allegro that follows the lovers'
first ecstatic greetings.

The goddess of love demands: let it be night, so that she may illuminate it, ( She hastens to the
torch. ) where she has banished your light. ( She takes the
torch from the door. ) Go to the watchtower: and there watch well. This light-- even if it were the light of my life-- laughing I do not hesitate to quench it. ( She throws the
torch to the ground, where it gradually goes out. )
